Centric 320.51042F Disc Brake Rotor - Front

Centric GCX Front Brake Rotor for Genesis, Kia, and Hyundai

The Centric GCX Elemental Protection Disc Brake Rotor, part number 320.51042F, is a front vented rotor built for select Genesis, Kia, and Hyundai applications. It combines a fully coated disc finish with a coated hat to help resist corrosion on exposed surfaces while maintaining a smooth braking surface.

Compatible With 2017 Genesis G80 front, 2016-2017 Kia K900 front, 2012-2016 Hyundai Genesis front, and 2011 Hyundai Equus front, this rotor is sized for vehicles that use a 13.583-inch outside diameter, 5-lug mounting pattern, and floating disc mounting. The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on corrosion protection and consistent rotor geometry for everyday brake service.

Product Details

Centric GCX Elemental Protection Disc Brake Rotors - Full Coating are built for drivers who want a direct-fit front rotor with corrosion-resistant surface treatment. This rotor measures 2.228 inches in overall height, has a 2.717-inch center hole diameter, and uses a 5.681-inch hat ID. The coated finish helps protect non-friction surfaces, while the smooth braking face supports even pad contact during normal service intervals. Part number 320.51042F is a fitment-specific rotor for select Genesis, Kia, and Hyundai front brake applications.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Issues This Rotor Can Address

• Front rotor wear that has reached discard thickness
• Brake pulsation caused by rotor surface irregularity
• Corrosion on exposed rotor and hat surfaces
• Noise from uneven pad-to-rotor contact
• Reduced braking consistency from heat-worn rotors

Installation Notes and Fitment Tips

Verify rotor dimensions, hub fit, and bolt pattern before installation. This front rotor is listed for 2017 Genesis G80 front, 2016-2017 Kia K900 front, 2012-2016 Hyundai Genesis front, and 2011 Hyundai Equus front. Confirm pad condition, caliper operation, and hub surface cleanliness during brake service to help ensure proper rotor seating and braking performance. Part number 320.51042F should be matched to the vehicle’s front axle application only.

Quality Assurance

Centric GCX rotors are engineered with coated surfaces and application-specific dimensions for direct replacement use on listed vehicles. The fully coated construction and vented design support corrosion resistance and consistent service fitment for the specified Genesis, Kia, and Hyundai models.
